TECHNICAL FIELD

The present invention relates to a sanitary installation with a panel-shaped base body, in particular for mounting on a ceiling, a wall or a floor, which carries at least one water conduit and at least one functional structural part.

BACKGROUND OF THE INVENTION

Sanitary installations of this type known on the market comprise large panel-shaped base bodies (mounting panels) of metal, in which a large number of shower elements are combined with the necessary connecting lines and optionally with the fixtures controlling the water flow. The panel is pre-installed as a unit and can be mounted complete, for example on a bathroom wall. From the building side, all that is required are simply the corresponding domestic water connections. Such sanitary installations have an optically pleasing design and can also easily be fitted later with shower elements, where none previously existed, without for example having to cut channels in the structural wall for the concealed laying of supply lines.

The present invention is directed to resolving these and other matters.

SUMMARY OF THE INVENTION

An object of the present invention is to modify a sanitary installation of the type mentioned in the introduction so that it is functionally and/or aesthetically more efficient.

This object may be achieved according to the invention in that the panel-shaped base body is made of a transparent material at least in the region between the water conduit and the user side.

According to the invention the advantages of the known sanitary installations mentioned in the introduction, namely the ease of installation and possibility of subsequently adding other fixtures, are thus combined with the advantages of an at least partly transparent base body. It has in fact been recognised that it is of great functional and/or aesthetic utility that the water conduits, in particular the water flow, are visible from the outside, in particular from the user side, at least when illuminated. In the context of the present invention the user side is understood as the side from which the sanitary installation is used, in particular actuated, and normally viewed. The actuating elements and/or the corresponding water outlets, in particular water outflows and/or shower heads, are installed on the user side.

In a particularly advantageous embodiment the water conduit is at least in part transparent. In this way even the water flow in the water conduit is visible from the outside.

Preferably the water conduit can be formed as a recess in the base body, so that no separate connection body, in particular no water pipe, is required.

In a particularly simple way the base body can be composed of a front, user-side panel element and a rear panel element facing away from the user side, the contact surfaces of which are complementary to one another, wherein in at least one contact surface at least one recess is provided, which when the panel elements are assembled is capable of forming at least a part of the water conduit. In this way the water conduit can be realised in a simple manner if the corresponding recesses are made for example when shaping the panel elements or are subsequently machined.

In order in particular to realise rotationally symmetrical water conduits in a simple manner, oppositely facing recesses can be provided in the contact surfaces, which when the panel elements are assembled form the part of the water conduit in the longitudinal direction, in each case in particular about half.

Conveniently at least the front panel element can be made of a transparent material, preferably of translucent or frosted, also coloured, glass or plastic, in particular acrylic glass. If a translucent material is used the water conduit is immediately visible when viewed from the observer side. Frosted material on the other hand under suitable illumination provides an optically pleasing blurred impression of the water conduit on the user side of the base body. The panel elements can for aesthetic reasons or to indicate the function of the sanitary installation also be made of a coloured material, for example cold water showers which are used in particular as sauna showers can be made of blue glass. In addition the rear panel element can also be made of the same or a different type of transparent material. In this way the whole base body appears homogeneous. The water conduit is thus visible from the user side and from the side of the base body remote from the user. Thus, instead of being mounted on a wall the base body can also be placed in an optically pleasing manner in the centre of a bathroom for example, where it is accessible and viewable from all sides.

In order to achieve a water outflow simply and without additional structural parts, a part of the water conduit can comprise a plurality of water outlet nozzles, which are open to the user-side surface of the base body, in particular of the front panel element.

Preferably the part of the water conduit with the outlet nozzles can have a two-dimensional layout, in particular for the implementation of a shower head, and in particular can comprise a plurality of concentric annular closed water conduit parts of different diameters, which can be connected to one another via in particular radial connecting lines. In this way a simple water conduit becomes an optically pleasing two-dimensional water outflow.

Furthermore a region of the panel-shaped base body can be bent by an angle in particular between 60° and 90° with respect to a main region and the main region of the base body can be arranged vertically in the room, in particular on a wall, and the bent region can be fitted with a shower head, in particular an overhead shower. In this way the base body with the main region can be mounted on the wall or installed vertically on the floor, and the bent region then holds the overhead shower or incorporates the latter.

In order to illuminate the base body, in particular the water conduit, the base body, in particular the rear panel element, can comprise at least one receptacle for at least one lighting means, in particular a light-emitting diode. The lighting means can also emit light of different colours. For example, the lighting means can be controlled by means of a suitable control unit so that the emitted colour characterises the respective water temperature and/or the water flow. The lighting means can preferably be connected to an invisible power supply, in particular of electrically conducting plastic, which is incorporated homogeneously into the optical image of the base body.

The receptacle for the lighting means can be a groove in the base body, which extends at least in part along the water conduit. In this way the water conduit can be illuminated directly. With a transparent water conduit the water flow can thereby also be visualised in an optically pleasing manner.

In addition the base body, in particular the front panel element, can include at least one receptacle for the at least one functional structural part, in particular for an actuating element and/or a shower unit, in which the functional structural part can easily be installed.

It is to be understood that the aspects and objects of the present invention described above may be combinable and that other advantages and aspects of the present invention will become apparent upon reading the following description of the drawings and detailed description of the invention.

DETAILED DESCRIPTION OF THE PRESENT INVENTION

While this invention is susceptible of embodiment in many different forms, there is shown in the drawings and will herein be described in detail one or more embodiments with the understanding that the present disclosure is to be considered as an exemplification of the principles of the invention and is not intended to limit the invention to the embodiments illustrated.

In FIGS. 1, 2, 3, 4 and 9 a shower installation identified overall by the reference numeral 10 is shown with a panel-shaped base body 12 for installation on a wall (not shown). FIGS. 5 to 8 in addition show mutually perpendicular sections through the shower installation 10.

The base body 12 carries a mixer unit 14, shown in the bottom right-hand part of FIG. 1, and above this a side-mounted shower 16 and at the very top an overhead shower 18, which are connected via a plurality of water conduits 20, 22, some of which are discussed hereinbelow and are shown in each case in a sectional view in FIGS. 5, 6, 7 and 8.

An upper overhead shower region 24 of the base body 12 is bent by an angle of about 80° with respect to a lower vertical main region 26 in the direction of the user side 28 of the base body 12, as shown in the right-hand part of FIG. 1, so that the overhead shower region 24 extends virtually horizontally from the imaginary vertical wall, which in FIG. 1 is located to the left of the base body 12, into the room. The user side 28 is the side of the base body 12 from which the shower installation 10 is used, in particular actuated, and is normally viewed.

The base body 12 is with the main region 26 vertically mounted on the wall. In this connection the underneath of the base body can rest on the floor, though it can however also be suspended on the wall, with or without contacting the floor, or can be secured above to the ceiling of a room.

The overhead shower 18 illustrated in FIGS. 3 and 4, and which is described in more detail hereinbelow, is arranged in the overhead shower region 24.

The base body 12 is composed overall of a front, user-side panel element 30 and a rear panel element 32 facing away from the user side 28. The panel elements 30, 32 are rectangular plates of transparent frosted glass, which in each case comprise an angular section so as to form the main region 26 and the overhead shower region 24.

The surfaces facing towards one another (contact surfaces) of the front panel element 30 and of the rear panel element 32 are flat and lie flush against one another. The two panel elements 30, 32 are joined to one another, preferably bonded, at the contact surfaces.

A cold water conduit and a hot water conduit, both of which are not visible in FIGS. 1 to 9 on account of the frosted nature of the glass, run in the form of recesses 34, described in more detail in connection with the other shown water conduits 20 and 22, between the contact surfaces from the underneath of the base body 12 to the mixer unit 14. The mixer unit 14 is situated in a corresponding receptacle, not shown in more detail, in the lower region of the vertical main region 26 of the base body 12. The ends of the cold water conduit and hot water conduit remote from the mixer unit 14 are in a known manner detachably connected to corresponding domestic water conduits (not shown), which lead from the wall, floor or ceiling.

From the mixer unit 14 a short side-mounted shower water conduit 20 shown in sectional view in FIGS. 5 and 6 and which is formed by two recesses 34, runs between the contact surfaces vertically upwards to a receptacle opening 36 for a side-mounted shower head 38 of the side-mounted shower 16, which is located somewhat above the mixer unit 14 in the vertical main region 26 of the base body 12.

Also, an overhead shower water conduit 22 likewise illustrated in FIGS. 5 and 6 and similarly bounded by two recesses 34, runs from the mixer unit 14 between the contact surfaces, vertically parallel next to the side-mounted water conduit 20 upwardly to the overhead shower region 24 of the base body 12, where it transforms into an overhead shower conduit part 22 b shown in sectional view in FIGS. 7 and 8.

The overhead shower conduit part 22 b is likewise formed by corresponding recesses 34 between the contact surfaces, and extends over a surface for the implementation of an overhead shower. For this purpose three concentric annular closed water conduit parts 22 c of different diameters are connected to one another via radial connecting lines, which are not shown in FIGS. 1 to 9 (cf. FIG. 7).

All water conduits 20, 22 in the base body 12 have in each case an overall round cross-section; this can be recognised in FIGS. 5 to 8. They are formed in the longitudinal direction in each case half and half by two oppositely facing recesses 34, which in each case are of semicircular cross-section. The recesses 34 are formed in the contact surfaces of the front panel element 30 and of the rear panel element 32. Mutually corresponding semicircular recesses 34 fit together in the assembled panel elements 30 and 32 to form in each case one of the water conduits 20, 22. The water conduits 20, 22 are transparent since they are bounded by the panel elements 30, 32 themselves.

The annular water conduit parts 22 c of the overhead shower conduit part 22 b furthermore comprise, as is shown in FIGS. 3, 4, 7 and 8, in the front panel element 30 a plurality of radially running water outlet nozzles 40, which extend perpendicular to the user-side surface of the front panel element 30.

The side-mounted shower water conduit 20 terminates, as shown in FIG. 5, in a circular cylindrical receptacle opening 36 for the side-mounted shower head 38 of the side-mounted shower 16. The receptacle opening 36 is located in the front panel element 30, and extends from the contact surface there opposite the recess 34 of the side-mounted shower water conduit 20, which is located in the rear panel element 26, to the user-side surface of the front panel element 30, and is open on both sides.

In the region of the receptacle opening 36 there is also arranged in the contact area of the rear panel element 32, a two-dimensional circular cylindrical depression 42 around the recess 34 located there of the side-mounted shower water conduit 20, the diameter of which corresponds approximately to the external diameter of the receptacle opening 36 and which is concentric to the axis of the receptacle opening 36.

The receptacle opening 36 furthermore comprises an internal thread, into which is screwed a pipe connection piece 44 of the side-mounted shower head 38, which in turn has a corresponding external thread. The pipe connection piece 44 starts from a base side, facing towards the front panel element 30, of a rotationally symmetrical installation body 46 concentric to its axis. When the pipe connection piece 44 is screwed in the installation body 46 lies with its base side facing towards the base body 12 against the user-side surface of the front panel element 30.

Between the base side of the installation body 46 and the user-side surface of the front panel element 30 there is also arranged a circular flat gasket 48, which is installed in the front panel element 30 and in the base side of the installation body 46 in each case in a sealing groove provided there, which is arranged concentrically to the axis of the pipe connection piece 44.

In the interior of the pipe connection piece 44 a water chamber 50 is provided on the side facing towards the side-mounted shower water conduit 20, onto which chamber is joined concentrically in the axial direction a plug-in receptacle 52 for a somewhat tubular-shaped plug-in connection 54 secured, preferably screwed in there, of the side-mounted shower head 38. The plug-in receptacle 52 terminates in a hemispherical, outwardly open space, into which projects the water inlet region of the side-mounted shower head 38.

In addition the rear panel element 32 comprises in the main region 26 of the base body 12 two vertically running receiving grooves 56 for a plurality of white light-emitting LEDs 58. The receiving grooves 56 are shown in FIGS. 2, 5, 6 and 9. The light-emitting diodes 58 are simply shown in FIGS. 5 and 6. The receiving grooves 56 extend along the side-mounted shower water conduit 20 and along the part of the overhead shower water conduit 22 running in the main region 26.

In the overhead shower region 24 the rear panel element 32 also comprises three annular running concentric receiving grooves 60, which are associated with the annular water conduit parts 22 c of the overhead shower conduit part 22 b of the overhead shower water conduit 22. In each receiving groove 60 four light-emitting diodes 58 are arranged at the corners of a respective imaginary square; this is shown in FIG. 9. The three imaginary squares are concentric and have parallel sides.

The receiving grooves 56 and 60 are recessed out respectively in the main region 26 on the rear side facing away from the user side 28, and in the overhead shower region 24 on the upper side of the rear panel element 32. They are open on the side facing away from the front panel element 30, i.e. on the side of the base body 12 facing away from the user. From the open side the light-emitting diodes 58 are inserted into the receiving grooves 56 and 60 and fixed in situ, as illustrated in FIGS. 5 to 8. The light-emitting diodes 58 are connected via known invisible power supply lines, preferably of electrically conducting transparent plastic, which are not shown in FIGS. 1 to 9, to a conventional control and power supply unit, which is likewise not illustrated.

As soon as the light-emitting diodes 58 are supplied with current they illuminate, from the rear side facing away from the user and from the upper side of the base body 12, the corresponding water conduits 10, 22. In this way the water conduits 10, 22, preferably even the water flows, are visible at least when seen from the user side 28. In addition the frosted glass is also illuminated diffusely by the light-emitting diodes 58 in a region around the water conduits 20, 22.

To install the shower installation 10 described above, this is first of all prefabricated as a unit. To this end the panel elements 30, 32 are injection moulded or cast, in which connection the recesses 34 for the water conduits 10, 20 for the cold water and hot water conduits, as well as the receiving grooves 56 and 60 for the light-emitting diodes 58, the receptacle for the mixer unit 14 and the receptacle opening 36 for the side-mounted shower 16, are formed at the same time. The internal thread is also formed in the side-mounted shower. In addition the power leads for the light-emitting diodes are laid, in particular pressed into place. Following this the panel elements 30 and 32 are bonded firmly to one another via their contact surfaces.

The mixer unit 14 and the side-mounted shower 16 are then installed on the panel elements. To install the side-mounted shower 16, the installation body 46 with the pipe connection piece 44 in front is first of all screwed into the receptacle opening 36. The side-mounted shower head 38 with its plug-in connection 54 is then inserted, preferably screwed, into the plug-in receptacle 52 of the pipe connection piece 44. The light-emitting diodes 58 are also inserted into the receiving grooves 56 and 60 and connected via the power lines to the control and power supply unit, which is likewise mounted on the base body 12. The prefabricated shower installation 10 is then secured complete in one piece to the wall, to the floor and/or to the ceiling, the hot water conduit and the cold water conduit being connected to the domestic water pipes already existing in or on the wall, floor or ceiling. In addition the control and power supply unit for the light-emitting diodes 58 is connected to a power supply line, which is likewise already laid in or on the wall, the floor, or the ceiling.

In a second example of implementation, illustrated in FIGS. 10 to 13, those elements that are similar to the corresponding elements of the first example of implementation described in FIGS. 1 to 9 are identified by the same reference numerals plus 100, so that as regards their description reference should be made to the details given in the first example of implementation. This second example of implementation differs from the first in that the panel elements 130 and 132 are not made of frosted glass but instead of transparent glass. Accordingly the hot water conduit 170, the cold water conduit 172, the side-mounted shower water conduit 120 and the overhead shower water conduit 122 together with their annular water conduit parts 122 c and the radial connecting lines 122 d (FIG. 12) are visible from outside as well as from the user side 128 (FIG. 13) and also from the side (FIGS. 11 and 12) of the base body 112 remote from the user, without having to be illuminated by the light-emitting diodes, which for the sake of clarity are not shown in FIGS. 10 to 13. Likewise, the receiving grooves 156 and 160 for the light-emitting diodes and the light-emitting diodes in the second example of implementation are visible from the user side 128 and from the side remote from the user. When illuminated by the light-emitting diodes, in contrast to the first example of implementation, in the second example of implementation the contours of the water conduits are outlined more sharply and the optical effects produced by the flow of water are more clearly visible. In FIG. 13, which shows the shower installation 110 from the user side 128, the external fixtures and fittings of the mixer unit 114 and the side-mounted shower 116 are not illustrated for the sake of clarity.

In all examples of implementation of a shower installation 10; 110 described above, the following modifications inter alia are possible:

The invention is not restricted to use in shower installations. Rather, it can also be employed in other types of sanitary installations, in particular in bathtub, sink, wash-hand basin or WC fixtures and fittings.

The panel-shaped based body 12; 112 can, instead of being mounted on a wall, can also be mounted only on the ceiling or in a freestanding manner on the floor in a room.

Also, only one water conduit 10, 22; 120, 122 or a plurality of water conduits, or water conduits of a different type to the described water conduits 10, 22; 120, 122, can be provided. For example, a WC feed water pipe can also be provided.

In addition, a separate water pipe can be incorporated as a water conduit into the recesses 34; 134. The whole water pipe or at last partial regions thereof can be transparent.

The recesses 34; 134 for the water conduits 20, 22; 120, 122 can, instead of in each case being arranged half and half, also be arranged in a different proportion in the two panel elements 30, 32; 130, 132. They can also be provided entirely in one of the panel elements 30; 130 or 32; 132.

The panel-shaped base body 12; 112 can, instead of being formed completely of glass, also be formed of glass only in the regions between the water conduits 20, 22; 120, 122 and the user side 28; 128. For example, also only the front panel element 30; 130 can be of a transparent material.

Instead of being made of glass, the base body 12; 112 can also be of another type of transparent, in particular coloured, material, and can preferably be made of transparent or frosted plastic, in particular acrylic glass.

The base body 12; 112 can also be formed from a single element.

The panel elements 30, 32; 130, 132 can, instead of being formed in the shape of rectangular plates, also be formed as plates of other shape, in particular polygonal, round or oval plates.

The contact surfaces of the panel elements 30, 32; 130, 132 can, instead of being flat, also be bent complementary to one another, so that they rest flat against one another.

The panel elements 30, 32; 130, 132 can, instead of being bonded to one another, also be joined to one another in some other way. For example they can also be pressed against one another and fixed with screws or clamps.

The upper region 24; 124 of the panel-shaped base body 12; 112 can, instead of being bent by about 80°, also be bent at a different angle, preferably between 60° and 90°, with respect to the main region 26; 126. A smaller or larger angle can however also be chosen. The base body 12; 112 can also be completely flat. It can for example be aligned vertically and fitted exclusively with side-mounted showers 16; 116, or can run horizontally along the ceiling and be fitted exclusively with overhead showers 18; 118.

The receiving grooves 56, 60; 156, 160 for the light-emitting diodes 58 can, instead of being arranged in the rear panel element 32; 132, also be arranged in the front panel element 30; 130 or along the contact surfaces.

Instead of the receiving grooves 56, 60; 156, 160, individual hole-shaped receptacles can also be provided for the light-emitting diodes 58.

Instead of or in addition to the light-emitting diodes 58, light guides can also be installed in the receiving grooves 56, 60; 156, 160, which are lit by corresponding lighting means, in particular with light-emitting diodes 58 arranged individually in the receiving grooves 65, 60; 156, 160.

Instead of the light-emitting diodes 58, other types of lighting means can also be used. Instead of or in addition to the white light-emitting LEDs 58, lighting means emitting light of other colours can also be provided. For example, light-emitting diodes producing different colours can be variably controlled so as to illuminate the shower installation 10; 110, in particular the water conduits 20, 22; 120, 122, in different colours. Preferably a light characteristic of a particular water parameter, in particular the water temperature and/or the flow rate, can be emitted. In particular hot water can be identified by the colour red and cold water by the colour blue. Also, when water is flowing the corresponding water conduit 20, 22; 120, 122 can be illuminated green, and when the water is turned off, can be illuminated red. A change of colour can however also be effected simply for purely aesthetic reasons.

In particular, in the second example of implementation the lighting means can also be omitted entirely.
